I guess that a problem with the current beta. I noticed this today during testing. It affects only new records that were created by clients and not admins. The server_id is missing in these records. Will have to take a look at the code what has caused this.

1) Cn you create items, when you are logged in as admin?
2) Can you create items when you are logged in as a client when you set a limit for a specific item.
3) Can you create items when you are logged in as a client when you set no limit for a specific item (-1).
4) Create a new client, can you craete items for him?
